UndetectedGPT
UndetectedGPT is a content-creation platform designed to help users generate or convert text so that it is indistinguishable from human-written material and avoids detection by AI-detector tools. The platform offers three core tools, AI Humanizer, which takes existing AI-generated text and reworks it to emulate human writing style with natural flow, tone variation and less mechanical structure; AI Stealth Writer, which generates new text from prompts while optimizing it to pass undetected by popular AI-detection systems; and AI Detector, which evaluates your text against multiple detectors and provides a score and analysis of how likely the text is to be flagged. Users can paste AI-generated content to be "humanized," choose a tone (casual, balanced, technical, formal), and then output a final version claimed to present “100% human-written” results for publishing, academia, or marketing, while remaining optimized for SEO and readability.

AI Detector Pro (AIDP)
We scour the latest outputs from ChatGPT and other AIs every day and constantly update our recognition algorithm. If you find an AI detector that performs better, send us the results for your money back.
AIDP detects AI in English, Spanish, and German documents. From there, it highlights text in your document that triggers AI detectors. For English text, it also shows you text that AI models predict and and highlights overused AI words and phrases.

Ryter
Ryter.pro is a web-based writing tool that helps users transform AI-generated text into natural, human-like writing. Its core feature rewrites machine-written content so it reads more like a human wrote it, preserving the original meaning while changing style, tone, and structure to make it difficult for AI-detectors to flag. It also includes a content detection module and other text-processing utilities. With a simple workflow, you paste in your AI-generated text, press “Humanize,” and receive a rewritten version that aims to bypass detection systems such as Turnitin, GPTZero, and Originality.ai. Ryter.pro emphasizes privacy: your content is not stored on its servers, and processing happens in real time before being deleted. It supports a REST API, enabling integration into automated workflows, useful for writers, marketers, or developers who need programmatic access.
